-LRB- CNN -RRB- -- A Russian jetliner crashed on landing in the city of Kazan , killing all 50 aboard , authorities there reported Sunday .

Tatarstan Airlines flight 363 carried 44 passengers and a crew of six , Emergency Situations Ministry spokeswoman Irina Rossius said . There were no survivors .

The dead included Lt. Gen. Alexander Antonov , the regional chief of Russia 's Federal Security Service , and Irek Minnikhanov , the son of Tatarstan regional President Rustam Minnikhanov , Russia 's state news service RIA Novosti reported .

A British national was also among those killed , the UK foreign ministry said .

The Boeing 737 took off from Moscow 's Domodedovo International Airport , about 700 kilometers -LRB- 450 miles -RRB- west of Kazan , Rossius said .

There was no immediate indication of the cause of the crash , which occurred about 7:25 p.m. , the ministry said . Russia 's Interstate Aviation Committee has launched an investigation , and the U.S. National Transportation Safety Board and Boeing are assisting .

Boeing said it `` extends its deepest condolences to the families of those who perished . ''

The jet was 23 years old and had been in service with at least eight airlines , including Air France , Uganda Airlines and Bulgaria Air , according to aviation industry websites .

In a November 2012 flight , it was forced to cut short a flight to Moscow and return to Kazan after losing cabin pressure , according to the website AeroInside .

Russia has tried to improve its checkered reputation for air safety in recent years .

In 2011 , then-President Dmitry Medvedev grounded two classes of Soviet-era aircraft after a pair of crashes that killed more than 90 people , including a charter plane crash that killed an entire professional hockey team .

Medvedev said Russia would have to upgrade its aircraft fleet , step up safety standards and radically cut the number of airlines .
